In Islamic demonology, Thabr (ëèñ) is one of the five sons of Iblis mentioned in Quranic commentary on Surah 18:51, which speaks about the offspring of Iblis. The devil is further mentioned in a hadith by Muslim ibn al-Hajjaj. He is a devil who causes calamities and injuries. His four brothers are named: Awar (çùÃÂñ or ÃÂãùÃÂçñ), Zalambur (òÃÂÃÂèÃÂñ), Sut (àóÃÂ÷), and Dasim (ïçóà). Each of them is linked to another psychological function, which they try to encourage to prevent humans spiritual development.
